Web API Service
To access a Web API service from the client, use the createStore method which is part of the DevExtreme.AspNet.Data extension. This extension also allows you to process data for DevExtreme widgets on the server. The server-side implementation is available under the DataGridWebApiController.cs tab in the ASP.NET MVC version of this demo.
To notify the DataGrid that data is processed on the server, set the remoteOperations option to true.
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
